` cannoiimrnnwnrnnourorr' vALv'ri Foitsoinar'oirn'rziiivs Application iilednecmber Y This inventi'onrelates toA soda fountains and moreparticularlyto valve mechanisms [bywhich the flow of carbonatedwater is Y controlled. It is well known in dispensing 5 soda,v water that the `water when first drawn into the glass must not disturb the syrup therein andjthat thereafter'itis preferable to discharge a fine stream under full pressurethat will pass through the entire liquid `lo contents.of-'theglassrand thoroughly incorf porate the'- syrup at the bottom ofi the glass `v with the carbonated water.-

It is an objectofv theA present invention thereforezto provide a: sodaw'ater dispensduits and leak-proof valve mechanisms/by i vwhich the ifuidmay be allowedto pass 'through either of 'these conduits I and by whichv both conduits will be automatically V closed when not desired for use. v

'It-is a further object ofthe present in-l vention -to' provide a" valve' mechanism for controlling-vthelflow of liquid through the" j conduits; the valve mechanismbeing dis-` ator may be' left free1 for other duties.

A further object of the 'invention' resides in *the provision of a' valve Vmechanism coin prising relatively few parts which is free fronrleather'washers andthe like, and which is therefore` strongand durable in operation.

/ -Otherv objects and'advantages of theinf ventio'n l will: be"` apparent` from the follow# ing description taken inconnection vwiththe accompanying drawing in vwhich f Figure lis a fragmentary lrear View of a1 soda fountain. i

Referri'ngto the drawingsiny` greater detail the l'numeral j 1fdesignates' al i sodaJ fountain ofconvention'altype provided with a countei` 2, syrup compartments"3"and supported uponafloor 4.- Ordinarilythepresent' ty'pe of soda fountains are'p'rovided with acplu'rality off faucets at there'ar thereof adm jacent the topY whicharefhairdoperated by the sodal fountain boy; Thesefaucetsy are ing device including inner andl outer con-V I"posed adjacent the' bottom "ofthe fountain rather 'than in a faucetvand `being `operated by the fo'ot,whereby'l both hands'ofthe oper- Figures 5 and 6 are. fragmentary longi-- tudin'al *sections* showing different positionsv 2, 1926." Serial No. 152.2()0` often leaky and,l of course, Arequire one hand of the. attendant in operating the same.

Inlieu of vsuch construction I have provided-conduits for leading the carbonated wateri'to the top of the Vsoda fountain'but controlled by the foot of the koperator adje cent the bottom of the fountain. Specifi- Gally the construction comprises an outer Aconduit 5 and an inner conduit 6 whichyare bent downwardly at their upper end as in- "dicated by the numeral 7 in simulation of an* ordinary faucet and to permit fluid to'frun into aglass held thereunder. Y

.The outer i conduit isA bu'lged voutwardly in the form of a `sphere18lo`cated justbelowthe floor on which the fountain 'is supported and* itv is adjacent this lbiilgedlportion'that the valve *controlling `mechanisml and the 'means for operating the same are located.v

Thel valve operating mechanism comprises acylinder 9 located on the'interior ofA the y conduit a 5 and carrying `a 'spider' '10 `which encircles'the inner conduit 6; Attached :todop- .posite sides of f the cylinder 9- and 'operating which a foot operated lever'lS ispivoted.l Thislever 13 is normally held in raisedpo# sition by 'means of'spring 13Tv Interp'o'sed between the cylinder 9 land 'the walls :of the outer conduit 5 arek plates 9 which 'are' vof sufficient lengthto cover theslots 11 irrespect'vel of the longitudinal position of l the cylinder' 9 within `th'ewconduit, and-'thereby srving toprevent leakage through these s ots.

means of `legs vla is a valve 'disc 15 whichis adaptedfto cooperate rwithafvalve seatfrl formed at the'lower end oftheouter'conduit 5.* This disc valve 15:of`co'urse, operates when in'itsclosedposition tov shut off the Rigidly connected with thel cylinder'9"by passage of Huid throughthefconduit 5,*and

centrally fixed on this disc Ais a plug valve 17 which fits within the inner' conduit' 6 and when in eitherof the position'sshown in Figures 3 'and 5 closesoff the passage of fluid" upwardly mouth 21 formed on the inner conduit 6. rIhis annular valve member when at its extreme upper limit as shown in Figure 3 or at an intermediate position as shown in Figure 5 will permit the passage ot fluid past the outer wall ot' the inner conduit 6; but when in its lower" position as shown in Figure (3 its engagement with the bell mouth 21 will shut ott the passage ot fluid through the cent'al opening Q0 and around the exterior of the conduit 6, but will in no way interfere with the passage of fluid through the interior of the conduit G which is open in this position of the annular valve member due to the fact that the plug 17 is withdrawn therefrom.

IYhile the operation ot the valve mechanism has been described in connection with the description ot the several partl it may nevertheless` be well to brietly summarize this action. lith the toot lever 13 in raised position caused by spring 13 the valve mechanism takes the position shown in Figure 3 with the disc 15 seated upon its seat 16, plug 17 located within the inner conduit G and the annular valve member 19 disposed above the bell mouth 21. It now, it is desired to discharge carbonated water into a glass in a relatively large stream the foot lever 13 is pressed downwardly a short distance so as to move the disc valve 15 away trom its seat 16 as'shown in Figure 5. This position of the valve 15 permits the water to pass around the edges of the disc, around the outside of the bell mouth 21, and through the opening Q0 in the valve member 19 and upwardly to the faucet 7. It it is now desired to direct a line jet of water into the glass the foot lever 13 is moved downwardly to its lower limit which carries the valve mechanism to the position shown in Figure 6 at which time the disc valve 15 rests upon its support; 18, the plug valve 17 is withdrawn .trom the inner conduit 6. and the annular valve member 19 seats on the bell mouth Q1. The plug 17 being withdrawn from the conduit G and the annular valve member 19 being seated upon the bell mouth 21 the carbonated water is allowed to pass upwardly through the conduit (i. but is prevented 'troni passing into the conduit- 5 and therefore allows a tine jet oi water to be projected into the glass held beneath the curved upper end 7 of the pipes. lVhen the toot lever 1.3 is released, of course, the spring 13 will raise the same to its upper liinitthereliiy bringing the valve mechanism to a position shown in Figure 3 and closing oli4 entrance to both the outer and inner conduits 5 and 6.

From the foregoing description taken in connection with the accompanying drawings it will be apparent that I have devised a liquid dispensing device especially adapted for soda fountains which may be operated by the foot of the soda fountain attendant,

thereby leaving both hands free lo manipulate 0'lasses and the like; that is formed ot relatively few parts; that does not involve the use or' leather washers, gaskets and the like, and is therefore proof against wear such as encountered in ordinary soda i'ofintain valves; and which is entirely leali-prooi'.

In accordance with the paient statutes l have described what I now believe to be the best enibodiment oi the invention; but I do not wish to be understood thereby as limiting myself or the scope oi the invention. as many changes and modifications may be made without departing trom the spirit oi the invention: all such I aim to include in the scope of the appended claims.
